Linux Networking/Token Ring

Token ring device names are `tr0', `tr1' etc. Token Ring is an IBM standard LAN protocol that avoids collisions by providing a mechanism that allows only one station on the LAN the right to transmit at a time. A `token' is held by one station at a time and the station holding the token is the only station allowed to transmit. When it has transmitted its data it passes the token onto the next station. The token loops amongst all active stations, hence the name `Token Ring'.
